TBC point cloud cleanup help

Anyone know of a better way to cleanup #pointcloud data sets for TIN surfaces generated from #SX10 scan data in TBC? We did a few scans of bare land with a few areas of sparse weeds. We end up with holes and spikes in the TIN area and since this is over a 10 acre area, it is pretty tedious to try and omit all of the areas manually.

Hoping that TBC can be updated with a new surface correction utility for cleaning up data sets.

Thanks for the feedback. Couple things you could try is classifying the point cloud to extract just the ground points and see if that removes the weeds to create a better surface from. Also you could resample the point cloud to remove excess data and get a smoother surface.

Thanks Adam. I tried have resampled and my screen shot is only a small area. There gets to a point that if you resample your spacing size large enough, that it might have been more productive to map the area by conventional means. However, even if you resample at a larger spacing, you still end up with spikes and holes.

What would really help for this site and others is the ability to "weed" out any outliers within a user specified tolerance - within a certain radius or user defined area. I believe Realworks has this ability, but we don't have a license for it.

John. We have just started using the SX10 as a rental for a few jobs. We find the easiest way to get to surface is to create points in CAD tab and just "Topo" on the scan. Using station view and 3d view picking points on grass, dirt, gravel, roads, curb anything. Then turn off scans. Run breaklines using feature codes and proceed like old school. Classify regions in the beginning and sometimes classifying a classified region again to break it down into parts that can be turned off and on. I think the learning curve is to figure out when to use scan and when not to. Mainly we scan when its quicker to gather data or safer. Then pick points only. Maybe also experiment with that create grid feature. Make a 20 foot grid on a field and then just delete points that look bad. I'm not in front of TBC excuse my sloppy terms. Some ideas anyway. Hopefully our Boss buys us one soon! Good luck!
